cookiemech,

Thank you very much for your time and valuable response. I agree with your gas mileage philosophy, I know I've seen at least one compact car that got slightly better mileage with an automatic over stick. I just miss driving stick and figure it might make a long commute more entertaining.

I checked out the link above your post and it has some great info. It appears that this engine uses variable size buckets for mechanical valve lash as opposed to shim under bucket which I believe my Tundra has, and is very common on motorcycles. I haven't had my Tundra checked yet, and I dread the day I get that done. I do hope these modern mechanical means of valve lash do hold up for most of the life of the engine, of course considering no heavy abuse and good oil change practices.

Thanks again...
